PolitiFact, the Tampa Bay Times fact-checking project, has come under fire this week for a ruling that seems to contradict common sense. Yesterday, MSNBC's Rachel Maddow -- PolitiFact's most vocal critic -- went to town on the group for claiming that an assertion made by Florida Senator Marco Rubio was "mostly true" when it was, in fact, false.

In the statement in question, Florida Senator Marco Rubio said the majority of Americans were conservatives. In his statement, Adair admits that "the number was short of a majority." Yet PolitiFact arrives at the conclusion that Rubio's statement is "Mostly True."

Hating on PolitiFact has become something of a sport in political media circles, especially since the fact-checking shop (a Tampa Bay Times project) selected its controversial "Lie of the Year." But this new email exchange posted by one Tom Bruscino, a U.S. military historian, will probably make things even worse.
